SNOW-PLOW.

SPECIPICATIQN forming part: of Letters Patent No. 309,275, datedDecember 16, 1884. Application filed April 19, 1884. (No model.)

the locomotiveengine; and the objects of my improvements are, first, toprovide a system of cutters fastened to and forming a part of theplow-frame, so that a solid block of snow may be removed; second, toarrange for the raising and lowering of the point of the plow,

and by the use of a hinge or hinges to be able,

when desired, to place the plow upon the same horizontal level with thetruck platform; third, to afforda method of locking the plow in a firmposition to the truck-platform after the same has been loaded; fourth,to permit the withdrawal of the material upon the load ed plow andfurnish means for dumping the same upon either side of the track at anyde sired point. I attain these objects by the mechanism illustrated inthe accompanying drawings, in which" Figure 1 is atop plan View. Fig.2is a side view with the plow upon a horizontal level with thetruck-platform. Fig. 3 is a side View with the point of the plowlowered, ready for commencing work. Fig. t is a side view of the plowupon a longitudinal level with the truck-platform, but tilted laterallyfor the purpose of dumping the snow at the side of the track.

Similar letters refer to similar parts th roughout the several views.

A represents the platform, which in practice is mounted upon car-trucksthat by preference have small wheels in front and larger and bolted oneto each of the cross-beams A. in such manner that the push'bar D isfirmly held from lateral displacement,yet free to turn within thebearings formed by the joint union of the semicircular straps andcross-beams.

E is a bolster firmly secured to the push-bar near its rear end, and Eis still another bolster firmly secured to and made apart of the plowproper. This bolster E has a cylindrical bearing in the center, aroundwhich passes a semicircular strap, a, and by which the bolster issecured and made to turn within the concave bearing formed upon the topof the push-bar.

F are longitudinal plow-beamsbeveled upon the under side at their frontends, so that when will be presented to the snow-drift.

F is a cross-beam near the forward end, and

F is the, rear crossbar by which the plowbeams are firmly united.

In practice the entire frame-work that comes in contact with the snow iscovered with metal or other suitable material, and by which the floor ofthe plow is formed.

Midway the length of the plow-beams, and upon the under side of thesame, is firmly secured the bolster E, thus fastening the plow to thepush-bar in such manner that it can be rocked upon the same in thedirection of its length.

G is a stop placed between the beams F,

and against which (in the act of plowing) the forward end of thepush-bar rests. H are vertical posts, mortised one intocach of theoutside plow-beams near their rear ends, and H are braces placed at anangle to the posts H, and stepped into the beams F, so as to make theback end of the plow secure.

I are beams running parallel with beams F, but above the same.

I is a cross-beam uniting the rear ends of beams I.

. J are braces, arched for strength, crossing each other diagonally andfirmly bolted to the beams I, for the purpose of keepingthis upper framein a rigid position.

K are metallic cutters secured to the forward ends of both the upper andlower frames of the plow. The upper ends of these cutters fall back, soas to make an oblique cut when the plow is forced into the snow-drift.

K is also a cutter running across and unit- ICO ing the front ends ofthe beams I. These knives or cutters act as supporting-bars for securingthe front end of the upper framework in a firm position.

In order that the plow may be prepared for the shock incident to the endthrust when encountering a heavy body of snow, gains are made in thebeams F, as at f, so that the shoulder of the gain will impinge againstthe forward end of the sills of the truck-platform. The hinged posts Bare also notched, as at b, so that a shoulder is formed, which extendsunder the rear end of .the plow when ready for work, and holding it inthe position shown in Fig. 3. Other notches are made in these hingedposts, as at b, and by means of which the plow is held upon a horizontallevel with the truck-platform, as shown in Fig. 2. If desired, a lever,wheel, rack, and pinion, or any other well -known device may be employedto facilitate the tilting of the loaded plow when in the act ofdischarging the snow. Any well known mechanical device may also be usedto raise and lower the plow, although, when properly balanced, it isbelieved that any mechanism will not be necessary for this purpose.Should it become necessary, in order to carry a heavier load than theopen plow will admit of, doors or other appliances may be used upon thesides, so as to inclose the whole or a part of the side opening untilthe time for dumping.

The operation is essentially as follows: After placing the car-platformupon the necessary trucks, and having the plow mounted thereupon, ashereinbefore described, the coupling is in any well-known manner madewith the locomotive, the plow being forward of the same, with the rearelevated, so as to cause the forward end to dip, and after being securedin this inclined position by the use of the hinged supporting-posts therun is made, the plow forcibly thrust into the snow-drift, the knives,while materially lessening the friction, quickly separates the mass tobe removed from' the embankment, and as the impetus given promptly fillsthe plow, therear end can be lowered, and when the plow is secured fromrocking the whole can be withdrawn,(if the bank is too heavy to drivethrough,) when by the tilting of the plow the snow can be deposited uponthe side of the road out of the way, and the operation repeateduntil thepassage-way is cleared, all of which will be readily understood withoutfurther description.

Having now described my invention, what I claim as new, and desire tosecure by Iletters Patent, is

1.- The combination of the cutters, the plowbeams,the upper longitudinalbeams,the pushbar, the stop against which the push bar rests, and thetruck-platform, arranged and operating substantially as described.

2. The combination of the push-bar, the plow-beams, the cross-bolstersecured to the same, the hinged connection between the bolster andpush-bar, and the hinged plow-supporting posts at the rear end of theplow, all arranged and operating substantially as described.

3. The combination of the plow-beams, the push-bar, the bolsters E E,the latter hinged to the plow-beam, the truck-platform, and thecentrally-notched supporting-posts at the'rear end of the plow, allarranged and operating substantially as described.

4. The combination of the truck-platform, the plow-beams, thecross-supports A, the push-bar mounted upon the cross-supports, and thebolsters E E, all arranged and operating substantially as described.

5. The beveled plow-beam having the notches f, the posts H, braces H,beams I, cross-beams I, knife-bar K, and braces J, all arranged-andoperating substantially as described.
